Trend Officescan – Proof of concept

In April a Trend vulnerability was discovered. The Trend real time scan service can be exploited by running a scan on a long directory name. It’s surprising that this vulnerability was discovered and yet is still exploitable in the latest release of Trend — which I’ve confirmed today. What’s neat is someone who only has user level privilege on a machine would be able to halt the Trend service and then potentially run some nasty code.

Here’s a VB project that will generate a long directory name and then attempt to run the scan: Trend POC (I’ve also compiled the source for those who don’t have VB — rename the .exe_ to .exe)
